I have a Dell optiplex 755 and the previous hdd died. replaced the hdd with an identical size hdd(250GB). reimaged the drive and it was successful. I reboot the computer with new image and it never boots. The BIOS says that it sees the new drive as SATA 1 and SATA 0 is the optical-drive. I look in the boot sequence and it is not present. I have read other problems simalar to this one and have tried all the SATA operation choices from
RAID Autodetect / AHCI
RAID Autodetect / ATA
and then I disabled the Keyboard error report
and still nothing boots up. I also have upgraded the BIOS to version A22. I can see the drive from a BARTPE bootup and the image/contents is there but the drive just will not boot up. I have occasionally seen the drive in the boot sequence but it does not stay. I have realign the boot sequence so that the first and second boot devices are, optical-drive and then SATA but is does not boot.
Running out of ideas to make this work. Any advice would be helpful, Thanks!
